Lighting – We recommend a 400W/600W metal halide for vegative stages and a 600W HPS for flowering. Which light you choose will be dependent on the ambient temperature of the incoming air. The wattage of lighting will ultimately dictate your yield as well as your ventilation requirements. A higher yield will generally be achieved by being able to maintain growing temperatures/humidity within the ideal range for your plants rather than increasing light and thus heat output and being unable to keep deal with temperatures. Air cooling

The use of air cooled lights will reduce the exhaust ventilation requirements, but will require a separate fan for the reflectors.

We recommend the use of a thermostatically controlled fan speed controller to maintain your temperatures within the desired range.

Intake fans – The flow rates should be approximately 30-50% less than the exhaust fan(s) flow rate. This is to allow for the restrictions caused by carbon filters and to ensure negative pressure, when correctly set up your Trojan tent should be sucking in slightly. When using intake fans always have a passive intake (ducting without a fan) this will ensure that the tent can breathe and that you aren’t causing too much restriction on the intake.
